Centorr Vacuum Industries Sells Two High-Temperature Furnaces for Aluminum Nitride Production

Centorr Vacuum Industries announced it has shipped orders for two high-temperature sintering furnaces for 2015 delivery to a leading firm in the production of AlN substrates for the LED market in China.

The designs include CVI’s 2 cu ft graphite furnace for AlN sintering and a refractory metal furnace rated to 1850C for a secondary heating process. These new furnaces build on the success of CVI’s experience in non-oxide ceramics and include modifications made specifically for high-temperature sintering of advanced ceramics.

Centorr’s graphite furnace design includes robust Graphite Tube and Block elements designed for use to 2250°C, with a 4-sided hot zone and integral graphite retort for excellent temperature uniformity. The rigid graphite insulation design provides for long-term service even in the presence of process off-gassing and residual binder contamination, while the new dual-flow Sweepgas® system allows more effective “sweeping” away of the process offgassing. Furnace control is via PLC/Programmable Controllers with Centorr’s custom-designed HMI visualization interface.

Centorr Vacuum Industries Sintervac Non-Oxide design is available in sizes of 2,3,4.5,9,16,24, and 54 cubic foot volumes. The refractory metal furnace design, sized at 1 cu ft will be used for a specific part of the AlN process where a non-graphite hot zone is desired for material cleanliness. The system is rated to 1850C and offers temperature uniformity under +/- 3°C.

Centorr Vacuum Industries is a high temperature vacuum and controlled atmosphere furnace manufacturer with an installed base of over 6500 units worldwide. Their furnace offering ranges from large commercial and production units with hot zones over 3m x 3m, to smaller Lab and Research & Development furnaces for use at temperatures over 3500°C. They are located in Nashua, NH with a fully staffed Aftermarket Field Service group, and Applied Technology Center offering R&D support and toll production service.

Corning developing scratch-resistant glass that rivals sapphire

According to accounts from Corning Incorporated’s annual investors meeting in New York City late last week, the glass giant is developing a scratch-resistant glass that rivals the strength of sapphire.

CNET reports that Corning announced work on the aptly-named Project Phire, a “developmental Gorilla Glass-like composite” that “combines the toughness of its Gorilla Glass smartphone displays with a scratch-resistance that comes close to sapphire.” The announcement comes on the heels of the company’s November Gorilla Glass 4 announcement, and not long after Apple’s sapphire-screen dreams crashed and burned.

(You may recall former editor Peter Wray’s 2013 post about the still-heated debate regarding sapphire vs. Gorilla Glass—as you should, since it’s one of the more popular posts here on CTT. If not, read it here. Head here and here to peruse the numerous other stories we’ve written on sapphire and Gorilla Glass, respectively.)

In the CNET post, Corning Glass Technologies president James Clappin says, “We told you last year that sapphire was great for scratch performance but didn’t fare well when dropped. So, we created a product that offers the same superior damage resistance and drop performance of Gorilla Glass 4 with scratch resistance that approaches sapphire.”

As for the technical 4-1-1 on Project Phire, details are slim (for now).

“We are working on a composite material that has Gorilla Glass 4-like damage resistance and sapphire-like scratch resistance,” writes Daniel F. Collins, VP of corporate communications, in an email. “We expect to be able to commercialize the new product later this year.”

In the meantime, the company has plenty to talk about.

The meeting was, of course, an opportunity for Clappin and other Corning execs to highlight the company’s 2014 performance (optical communications and environmental technologies were up 18% and 44%, respectively) and 2015 priorities (“positive momentum”), which include an “unwavering” commitment to innovation, according to a Corning news release. That innovation has brought about developments like the Iris glass showcased at the 2015 Consumer Electronics Show. The company says that the glass can significantly reduce the size of the average LCD TV, resulting in a television with “outstanding transmission” that’s “as thin as a smartphone.”

“2015 will be all about large-size LCD TVs,” Clappin says in the release. “This segment of the display industry grew more than 50% year over year on a unit basis in 2014, and our analysis shows that the average TV screen size is growing more than 1 inch per year. Importantly, every inch in screen-size growth equates to about 150 million square feet of additional glass demand.”

Advances in Advanced Ceramics and Coating Processing

This recently published Special Issue of Advanced Engineering Materials, guest-edited by Eugene Medvedovski (Calgary, Canada) and Nahum Travitzky (Erlangen, Germany), is dedicated to novel processing of advanced ceramics, composites, and coatings. This includes both the research and optimization of earlier developed processing routes, which improve the productivity and quality of the materials.

The issue contains 18 invited papers prepared by or with participation of the well-recognized ceramic specialists from academia and industry. The manuscripts cover different aspects of ceramic and coating processing, such as: preparation and use of special ceramic powders and precursors materials, colloidal processing, forming routes of different advanced engineering (ceramics, composites, and coatings) for a variety of applications, materials consolidation, studies of the influence of processing on structure and properties of the materials, and large-scale manufacturing. The results of some selected papers have been presented at international conferences, but some papers describe absolutely new results. Some papers cover the extensive studies conducted by the authors for a number of years and even implementation of the materials and processes with the features of industrial experience. The readers can see that the papers presented in this issue were prepared by the authors from different countries of North America, Europe, Asia, and Australia, and they demonstrate a successful collaboration between the organizations not only from one country, but also from other countries and even continents.

Advanced Ceramics in the Hunt for Comets-[CeramTec]

Piezoceramic multilayer actuators on board the “Rosetta” space probe

On 2 March 2004 at 08:17 CET, an Ariane 5 G+ booster rocket took off from the Kourou space centre in French Guiana. The mission: 67P/Churyumov–Gerasimenko. The payload: ESA’s 3-tonne “Rosetta” cometary probe including science experiments, the “Philae” lander – and8 piezoceramic multilayer actuators with a mass of 31.8 g.

Even at lift-off of the rocket booster 10 years ago, thepiezo actuators built into the “Philae” lander had to withstand the extreme vibrations and thermal shocks before leaving the Earth’s atmosphere. After achieving a near-Earth trajectory around the sun, “Rosetta” carried out several swing-by maneuvers persistently nearing its target: the comet 67P/Churyumov–Gerasimenko.

The probe spent part of the journey in hibernation mode – for 957 days in the freezing coldness of space, 660 million kilometers from the sun, only the on-board computer and some heating elements for the scientific payload were provided with energy.

According to plan, “Rosetta” was activated in January 2014 with the “Philae” lander being activated in March. After the meticulous and successful testing of all on-board instruments for their full operability, the probe will continue to close in on the comet from around two million kilometers to an eventual height of 10km. It is here that on 12 November 2014, a world’s-first should take place: “Philae” will detach from “Rosetta” and land on the comet 67P/Churyumov-Gerasimenko.

Both probe and lander will then explore the comet during its active phase together, providing ESA’s scientists with an insight into the chemical and isotopic composition of the early solar system.

One of the instruments that will be used on the comet’s surface is the MIDAS (Micro-Imaging Dust Analysis System), a high-resolution atomic force microscope that can image the fine structure of individual dust particles and can even make individual atoms “visible”. MIDAS is to investigate the dust on the comet’s surface, analyze the mineral composition and if possible provide information about the age and journey of the comet.


 

The piezoceramic multilayer actuators from CeramTec are responsible for guiding the extremely fine measuring needles in the MIDAS instrument: actuator fine positioning of the highly sensitive needles takes place with a precision of 4 millionths of a millimeter. This means that a surface square with side lengths of a maximum of 100µm (= thousandths of a millimeter) will be scanned with a resolution (accuracy) of 4nm (= millionths of a millimeter). 100µm corresponds roughly to the thickness of a sheet of writing paper – 4nm is 25,000 times less.

Piezo actuators are typically used in precise positioning systems, but that is not their only use. PZT actuators are used for precision guidance in many systems, from laboratory technology and car manufacturing to machine engineering. Even if not quite as spectacular as with “Rosetta” and “Philae” – when precision, speed and power are needed, piezoceramic materials offer interesting and reliable solutions when it comes to micro-positioning, valve control, vibration damping or acoustics.

We will only find out whether the “Rosetta” mission will be a success and if the “Philae” lander can begin its tasks on the 12 November at around 16:00 UTC – this is when the signal confirming the landing should reach the Earth, following a signal propagation delay of 28 minutes and 20 seconds.
